Toxic Blade

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects. At the beginning of target's turn, it immediately takes 1d6 poison damage, and the spell dissipates.

This spell's damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d6 acid damage to the target, and the damage the target takes increases to 2d6. Both damage rolls increase by 1d6 and 1d6 at 11th level and 17th level.
